The inclination of a line represents the angle it makes with the positive x-axis in a counterclockwise direction. In this case, the inclination is given as 0 radians, which means the line is parallel to the x-axis.

For a line parallel to the x-axis, the slope is 0. This is because the slope of a line is defined as the change in y-coordinates divided by the change in x-coordinates between any two points on the line. Since the line is parallel to the x-axis, the change in y-coordinates is always 0, resulting in a slope of 0.

Therefore, the slope of the line with an inclination of 0 radians is 0. The line is a horizontal line that does not rise or fall as x increases or decreases.

The final graph of the function y=x^2 after applying three transformations (a) shifting left by 2 units, (b) reflecting in the y-axis, and (c) shifting downwards by 3 units can be represented by the equation y = -(x + 2)^2 - 3. The graph is a downward-facing parabola shifted to the left by 2 units and downwards by 3 units.

The original function is y = x^2, which represents a standard upward-facing parabola centered at the origin. To apply the transformations, we follow the given order.

(a) Shifting left by 2 units: To shift the graph left by 2 units, we replace x with (x + 2) in the equation. Now the equation becomes y = (x + 2)^2.

(b) Reflecting in the y-axis: Reflecting the graph in the y-axis is equivalent to changing the sign of x. So, the equation becomes y = -(x + 2)^2.

(c) Shifting downwards by 3 units: To shift the graph downwards by 3 units, we subtract 3 from the equation. Therefore, the final equation is y = -(x + 2)^2 - 3.

This equation represents a downward-facing parabola that has been shifted to the left by 2 units and downwards by 3 units. The vertex of the parabola is at (-2, -3). A rough sketch of the final graph would show a symmetric curve opening downwards with its vertex shifted to the left and downwards from the origin.

The mean age of a randomly selected sample of 35 teachers is 42 years, which is different from the principal's claim that the mean age of the teachers is 45 years. This suggests that there may be a discrepancy between the actual mean age and the claimed mean age.

In hypothesis testing, we compare the sample mean to the claimed population mean to determine if there is sufficient evidence to reject the claim. In this case, the null hypothesis (H0) would be that the mean age of the teachers is 45 years, while the alternative hypothesis (Ha) would be that the mean age is not 45 years.

To assess the significance of the difference between the sample mean and the claimed mean, we can conduct a hypothesis test using statistical methods such as a t-test.

The test will provide a p-value, which represents the probability of obtaining a sample mean as extreme as the observed mean if the null hypothesis is true. If the p-value is below a predetermined significance level (e.g., 0.05), we reject the null hypothesis and conclude that there is evidence to suggest that the true mean age differs from the claimed mean age.

In this case, if the observed mean of 42 years significantly deviates from the claimed mean of 45 years, it suggests that the principal's claim may not be accurate, and the mean age of the teachers may be different from what is claimed.

The given hyperbola equation is in the standard form:

((y+2)^2 / 16) - ((x-4)^2 / 9) = 1

Comparing this equation with the standard form of a hyperbola, we can determine the center of the hyperbola, which is (h, k). In this case, the center is (4, -2).

The formula for finding the coordinates of the foci of a hyperbola is given by c = sqrt(a^2 + b^2), where a and b are the lengths of the semi-major and semi-minor axes, respectively. For the given hyperbola, a = 4 and b = 3. Plugging these values into the formula, we can calculate c:

c = sqrt(4^2 + 3^2) = sqrt(16 + 9) = sqrt(25) = 5

Since the hyperbola is centered at (4, -2), the foci will be located at (4, -2 + 5) = (4, 3) and (4, -2 - 5) = (4, -7).

For the equation of the asymptotes, we can rearrange the given equation of the hyperbola:

(y^2 - 6y) - 3(x^2 - 2x) = 18

By completing the square for both x and y terms, we obtain:

(y^2 - 6y + 9) - 3(x^2 - 2x + 1) = 18 + 9 - 3

Simplifying further, we get:

(y - 3)^2 - 3(x - 1)^2 = 24

Dividing both sides by 24, we get:

((y - 3)^2 / 24) - ((x - 1)^2 / 8) = 1

Comparing this equation with the standard form of a hyperbola, we can determine the slopes of the asymptotes. The slopes of the asymptotes are given by ±(b/a), where b is the length of the semi-minor axis and a is the length of the semi-major axis.

In this case, b = sqrt(24) and a = sqrt(8). Therefore, the slopes of the asymptotes are ±(sqrt(24) / sqrt(8)) = ±(sqrt(3)).

Using the slope-intercept form of a line, we can write the equations of the asymptotes in the form y = mx + b, where m is the slope and b is the y-intercept. Since the asymptotes pass through the center of the hyperbola (4, -2), we can substitute these values into the equation.

The equations of the asymptotes are y = ±(sqrt(3))(x - 4) - 2.

In , the coordinates of the foci for the given hyperbola are (4, 3) and (4, -7), and the equations of the asymptotes are y = ±(sqrt(3))(x - 4) - 2.

The total area between the curve and the x-axis over a given interval is the sum of the absolute values of all the individual areas.

To calculate the total area between the curve and the x-axis, we need to consider the areas both above and below the x-axis separately. First, we identify the x-values where the curve intersects the x-axis within the given interval. These points act as boundaries for the individual areas.

For each interval between two consecutive intersection points, we calculate the area by integrating the absolute value of the curve's equation with respect to x over that interval. This ensures that both positive and negative areas are included.

If the curve lies entirely above the x-axis or entirely below the x-axis within the given interval, we only need to calculate the area using the curve's equation without taking the absolute value.

The probability mass function for N is [tex]P(N = n) = (\frac{1}{2})^n[/tex], and the mean  E[N], is 0. This means that the expected value for the index of the first bid better than the initial bid, in this scenario, is 0.

What is the probability mass function?

The probability mass function (PMF) is a function that describes the probability distribution of a discrete random variable. In the case of N, the index of the first bid better than the initial bid, the PMF can be derived as follows:

[tex]P(N = n) = (\frac{1}{2})^n[/tex].

To determine the probability mass function (PMF) for N and the mean E[N], let's analyze the problem step by step.

Given:

To find the PMF of N, we need to calculate the probability that N takes on a specific value n, where n is a positive integer.

Let's consider the event that N = n. This event occurs if[tex]X_{1} \leq X_{0}, X_{2} \leq X_{0},...,X_{(n-1)} \leq X_{0},X_{n} \leq X_{0}.[/tex]

Since [tex]X_{0} ,X_{1}, X_{2} ,X_{3},...[/tex]are identically distributed random variables, we can calculate the probability of each individual event using the properties of the continuous distribution. The probability that[tex]X_{k} > X_{0}[/tex] for any specific k is given by:

[tex]P(X_{k} > X_{0})=\frac{1}{2}[/tex] (assuming a symmetric continuous distribution)

Now, let's consider the event that [tex]X_{1} \leq X_{0}, X_{2} \leq X_{0},...,X_{(n-1)} \leq X_{0}.[/tex]Since these events are independent,  their probabilities:

[tex]P(X_{1} \leq X_{0}, X_{2} \leq X_{0},...,X_{(n-1)} \leq X_{0},X_{n} \leq X_{0})=[P(X_{1} \leq X_{0}]^{n-1}[/tex]

Finally, the PMF of N is given by:

P(N = n) =[tex]P(X_{1} \leq X_{0}, X_{2} \leq X_{0},...,X_{(n-1)} \leq X_{0},X_{n} \leq X_{0})*P(X_{n} > X_{0})\\\\=[P(X_{1} \leq X_{0})]^{n-1}*P(X_{n} > X_{0})\\\\=(\frac{1}{2})^{n-1}*\frac{1}{2}\\\\=(\frac{1}{2})^n[/tex]

So, the probability mass function (PMF) for N is[tex]P(N = n) = (\frac{1}{2})^n.[/tex]

To calculate the mean E[N], we can use the formula for the expected value of a geometric distribution:

E[N] = ∑(n * P(N = n))

Since[tex]P(N = n) = (\frac{1}{2})^n.[/tex], we have:

E[N] = ∑([tex]n * (\frac{1}{2})^n[/tex])

To calculate the sum, we can use the formula for the sum of an infinite geometric series:

E[N] = ∑([tex]n * (\frac{1}{2})^n[/tex])

= ∑([tex]n * {x}^n[/tex]) (where x = 1/2)

[tex]\frac{d}{dx}\sum(x^n) = \sum(n * x^{n-1})[/tex]

Now, multiply both sides by x:

[tex]x\frac{d}{dx}\sum{x}^n = \sum(n * {x}^{n})[/tex]

Substituting x = [tex]\frac{1}{2}[/tex]:

[tex]\frac{1}{2}*\frac{d}{dx}\sum(\frac{1}{2})^n = \sum(n * (\frac{1}{2})^{n})[/tex]

The sum on the left side is a geometric series that converges to [tex]\frac{1}{1-x}[/tex]. So, we have:

[tex]\frac{1}{2}*\frac{d}{dx}(\frac{1}{1-\frac{1}{2}})=E[N]\\[/tex]

Simplifying:

[tex]\frac{1}{2}*\frac{d}{dx}(\frac{1}{\frac{1}{2}})=E[N]\\\\\frac{1}{2}*\frac{d}{dx}(2)=E[N]\\\\\frac{1}{2}*0=E[N]\\[/tex]

E[N] = 0

Therefore, the mean of N, E[N], is equal to 0.

The two indefinite integrals are given by; ∫cos(at/x^5) dx and ∫x² dx6- x

Part 1: The indefinite integral of cos(at/x^5) dx

The indefinite integral of cos(at/x^5) dx can be computed using the substitution method.

We have; u = at/x^5, du/dx = (-5at/x^6)

Rewriting the integral with respect to u, we get; ∫ cos(at/x^5) dx = (1/a) ∫cos(u) (x^-5 du)

Let's note that the derivative of x^-5 with respect to x is (-5x^-6). Therefore, we have dx = (1/(-5))(-5x^-6 du) = (-1/x)du

Now, substituting the values back into the integral, we get;(1/a) ∫cos(u)(x^-5 du) = (1/a) ∫cos(u) (-1/x) du

The integral can now be evaluated using the substitution method.

We have;∫cos(u) (-1/x) du = (-1/x) ∫cos(u) du

Letting C be a constant of integration, the final solution is; ∫cos(at/x^5) dx = -sin(at/x^5) / (ax) + C

Part 2: The indefinite integral of x² dx 6- x

The indefinite integral of x² dx 6- x can be computed by using the following method; (ax^2 + bx + c)' = 2ax + b

The integral of x² dx is equal to (1/3)x^3 + C.

We can then use this to solve the entire integral. This gives; (1/3)x^3 + C1 - (1/2)x^2 + C2 where C1 and C2 are constants of integration. We can then use the initial conditions to solve for C1 and C2.

A repeated-measures design has the maximum advantage over an independent-measures design in situation D.

When very few subjects are available and individual differences are large. In a repeated-measures design, each subject serves as their own control, which allows for the isolation of treatment effects from individual differences. This design is particularly beneficial when the sample size is small and individual differences are substantial, as it helps control for variability and increases statistical power, leading to more accurate results. In comparison, an independent-measures design involves separate groups of subjects for each treatment condition, making it more susceptible to the influence of individual differences, especially when the sample size is limited.

the vector equation for the object's position is: r(t) = (t + 2) i + (4e^(2t) - 8) j + (t^2 + 8t + 1) k. To find the vector equation for the object's position, we need to integrate the velocity vector function with respect to time.

Velocity vector function: v(t) = (1, 8e^(2t), 2t + 8). Initial position: F(0) = (2, -4, 1). Integration of each component of the velocity vector function gives us the position vector function: r(t) = ∫v(t) dt. Integrating each component of the velocity function: ∫1 dt = t + C1

∫8e^(2t) dt = 4e^(2t) + C2

∫(2t + 8) dt = t^2 + 8t + C3

Combining these components, we get the vector equation for the object's position: r(t) = (t + C1) i + (4e^(2t) + C2) j + (t^2 + 8t + C3) k. To determine the integration constants C1, C2, and C3, we use the initial position F(0) = (2, -4, 1). Substituting t = 0 into the position vector equation, we get: r(0) = (0 + C1) i + (4e^(0) + C2) j + (0^2 + 8(0) + C3) k

(2, -4, 1) = C1 i + (4 + C2) j + C3 k

Comparing the corresponding components, we have:C1 = 2. 4 + C2 = -4 => C2 = -8. C3 = 1. Therefore, the vector equation for the object's position is: r(t) = (t + 2) i + (4e^(2t) - 8) j + (t^2 + 8t + 1) k

Using spherical coordinates, the z-coordinate of the center of mass of a solid hemisphere with the given density function and mass is determined to be 7/12.

To find the z-coordinate of the center of mass, we need to calculate the triple integral of the density function over the solid hemisphere. In spherical coordinates, the volume element is given by ρ^2 sin(φ) dρ dφ dθ, where ρ is the radial distance, φ is the polar angle, and θ is the azimuthal angle.

First, we set up the limits of integration. For the radial distance ρ, it ranges from 0 to the radius of the hemisphere, which is a constant value. The polar angle φ ranges from 0 to π/2 since we are considering the upper half of the hemisphere. The azimuthal angle θ ranges from 0 to 2π, covering the entire circumference.

Next, we substitute the density function d = m into the volume element and integrate. Since the mass m is given as 7/4, we can replace d with 7/4. After performing the triple integral, we obtain the z-coordinate of the center of mass as 7/12.

This general solution satisfies the given differential equation y" - 6y + 9y = e³1 t² for t > 0.

The general solution of the given differential equation y" - 6y + 9y = e³1 t² for t > 0 can be obtained using the method of Variation of Parameters. It involves finding particular solutions and then combining them with the complementary solution to obtain the general solution.

To solve the differential equation using Variation of Parameters, we first find the complementary solution by assuming y = e^(rt). Substituting this into the differential equation gives us the characteristic equation r² - 6r + 9 = 0, which factors to (r - 3)² = 0. Hence, the complementary solution is y_c = (c₁ + c₂t)e^(3t).

Next, we find the particular solution using the method of Variation of Parameters.

We assume a particular solution of the form y_p = u₁(t)e^(3t), where u₁(t) is an unknown function.

Differentiating y_p twice, we get y_p'' = (u₁'' + 6u₁' + 9u₁)e^(3t).

Substituting y_p and its derivatives into the differential equation, we obtain u₁''e^(3t) = e³1 t².

To determine u₁(t), we solve the following system of equations: u₁'' + 6u₁' + 9u₁ = t² and u₁''e^(3t) = e³1 t².

By solving this system, we find u₁(t) = (1/9)t⁴e^(-3t).

Finally, the general solution is obtained by combining the complementary and particular solutions: y = y_c + y_p = (c₁ + c₂t)e^(3t) + (1/9)t⁴e^(-3t).

Next, let's simplify further:

J = ∫₀⁶ [(1/12)x (100 - (100/3)x + (100/36)x²) + (5/18)x (1000 - (1000/3)x + (100/3)x² - (100/27)x³)] dx

Now, let's expand and collect like terms:

Now, let's integrate each term:

J = [25/2x² + 250/3x² - 25/9x³ - 250/27x³ + 25/432x⁴ + 250/108x⁴ - 250/108x⁵] from 0 to 6

Substituting the upper and lower limits:

The interval [1,23] must be split at the location where the function inside the absolute value changes sign in order to express the integral [1,23] |x| dx as a sum of integrals without absolute values.

Since the function |x| in this instance changes sign when x = 0, we divided the interval as follows:

The equation is [1,23] |x| dx = [1,0] (-x) dx + [0,23] x dx.We may now assess each integral independently:

∫[1,0] (-x) dx = [-x^2/2] from 1 to 0 equals -(1 / 2) - (-1^2/2) = -0 + 1/2 = 1/2

∫[0,23] x dx = [x^2/2] 0 to 23 equals (232/2) - (0^2/2) = 529/2

Combining these two findings, we obtain:

∫[1,23] |x| dx = 1/2 + 529/2 = 530/2 = 265

The integral [1,23] |x| dx evaluates to 265 as a result.

Domain of the given function is R². It is a plane or a flat surface. The range of the function f(x,y) is (- ∞, 64].

The given function is f(x,y) = 8²-7y².The domain of the function is all possible values of x and y for which the function is defined. To find the domain of the given function, we have to set the restrictions, if any, on the variables (x and y) of the given function. As there is no restriction given on the variables x and y, the domain of the function is all possible values of x and y. Therefore, the domain of the given function f(x,y) is R² (i.e. all real numbers). The domain of the function is a plane or a flat surface.

Now, let's find the range of the function f(x,y).The range of the function is defined as all possible values that the function can take. So, we need to find all possible values of f(x,y).Since, f(x,y) = 8² - 7y²= 64 - 7y²We know that the maximum value of 7y² can be 0 if y = 0.So, the maximum value of f(x,y) is 64 and the minimum value of f(x,y) can be negative infinity as 7y² can take any non-negative value. So, the range of the function f(x,y) is (- ∞, 64]. Hence, the answer to the given problem is as follows: Domain of the given function is R². It is a plane or a flat surface. The range of the function f(x,y) is (- ∞, 64].

To find the equations of the tangent plane and the normal line to the given surface at the specified point, we'll first rewrite the equation of the surface in the form r = f(x, y, z). Answer : the equation of the tangent plane is: -x + y + (1/2)z + 6 = 0,r = (3, 2, -5) + t(-1, 1, 1/2)

Given equation: x - 2y + 2z + y = 16

Rearranging terms, we have: x + y - 2y + 2z = 16

Simplifying, we get: x - y + 2z = 16

So, the equation of the surface in the form r = f(x, y, z) is: r = (x, y, (16 - x + y)/2)

(a) Tangent Plane:

To find the equation of the tangent plane, we need the gradient vector of the surface at the specified point (3, 2, -5).

Taking the partial derivatives of f(x, y, z), we have:

∂f/∂x = -1

∂f/∂y = 1

∂f/∂z = 1/2

Evaluating the gradient vector at the point (3, 2, -5), we have: ∇f(3, 2, -5) = (-1, 1, 1/2)

Using the formula for the equation of a plane, which is of the form Ax + By + Cz + D = 0, we can substitute the point (3, 2, -5) and the values from the gradient vector to find the equation of the tangent plane:

-1(x - 3) + 1(y - 2) + (1/2)(z + 5) = 0

Simplifying, we get: -x + 3 + y - 2 + (1/2)z + (5/2) = 0

Rearranging terms, we have: -x + y + (1/2)z + 6 = 0

So, the equation of the tangent plane is: -x + y + (1/2)z + 6 = 0.

(b) Normal Line:

The direction vector of the normal line is the same as the gradient vector at the specified point, which is (-1, 1, 1/2).

The equation of a line passing through the point (3, 2, -5) with direction vector (-1, 1, 1/2) can be expressed parametrically as:

x = 3 - t

y = 2 + t

z = -5 + (1/2)t

So, the equations of the normal line are:

x = 3 - t

y = 2 + t

z = -5 + (1/2)t

Alternatively, we can express the equations of the normal line in vector form as:

r = (3, 2, -5) + t(-1, 1, 1/2)

Note: In both cases, t represents a parameter that can take any real value.

a. The object is moving to the left during the time interval (1, 3).

b. The acceleration is positive when the velocity is equal to zero.

c. The acceleration is positive during the time interval (1, 3).

d. The speed is increasing during the time intervals (-∞, 1) and (3, ∞).

To determine the object's motion on a horizontal coordinate line based on its directed distance function s(t), we need to analyze its velocity and acceleration.

a. When is the object moving to the left?

The object is moving to the left when its velocity is negative. Velocity is the derivative of the directed distance function s(t) with respect to time.

Let's find the velocity function v(t) by taking the derivative of s(t):

v(t) = s'(t) = d/dt ([tex]t^3 - 6t^2 + 9t[/tex])

Differentiating each term:

v(t) = [tex]3t^2[/tex] - 12t + 9

For the object to move to the left, v(t) must be negative:

[tex]3t^2[/tex] - 12t + 9 < 0

To solve this inequality, we can factorize it:

3(t - 1)(t - 3) < 0

The critical points are t = 1 and t = 3. We can create a sign chart to determine the intervals when the expression is negative:

Interval:  (-∞, 1)   |   (1, 3)   |   (3, ∞)

Sign:     (-)      |    (+)     |    (-)

From the sign chart, we see that the expression is negative when t is in the interval (1, 3). Therefore, the object is moving to the left during this time interval.

b. Acceleration is the derivative of velocity with respect to time.

Let's find the acceleration function a(t) by taking the derivative of v(t):

a(t) = v'(t) = d/dt ([tex]3t^2[/tex]- 12t + 9)

Differentiating each term:

a(t) = 6t - 12

To find when the velocity is zero, we solve v(t) = 0:

[tex]3t^2[/tex] - 12t + 9 = 0

We can factorize it:

(t - 1)(t - 3) = 0

The critical points are t = 1 and t = 3. We can create a sign chart to determine the intervals when the expression is positive and negative:

Interval:  (-∞, 1)   |   (1, 3)   |   (3, ∞)

Sign:     (+)      |    (-)     |    (+)

From the sign chart, we observe that the expression is positive when t is in the interval (1, 3). Therefore, the acceleration is positive when the velocity is equal to zero.

From the previous analysis, we found that the acceleration is positive during the time interval (1, 3).

The speed of an object is the magnitude of its velocity. To determine when the speed is increasing, we need to analyze the derivative of the speed function.

Let's find the speed function S(t) by taking the absolute value of the velocity function v(t):

S(t) = |v(t)| = |[tex]3t^2[/tex] - 12t + 9|

To find when the speed is increasing, we examine the derivative of S(t):

S'(t) = d/dt |[tex]3t^2[/tex] - 12t + 9|

To simplify, we consider the intervals separately when [tex]3t^2[/tex] - 12t + 9 is positive and negative.

For [tex]3t^2[/tex] - 12t + 9 > 0:

[tex]3t^2[/tex] - 12t + 9 = (t - 1)(t - 3)

> 0

From the sign chart:

Interval:  (-∞, 1)   |   (1, 3)   |   (3, ∞)

Sign:     (-)      |    (+)     |    (-)

We can observe that the expression is positive when t is in the intervals (-∞, 1) and (3, ∞). Therefore, the speed is increasing during these time intervals.

For f(x) to be a valid PDF, integrating f(x) dx over the support of x must be equal to 1. The above statement is true.

For a function f(x) to be a valid probability density function (PDF), it must satisfy two conditions:
1. f(x) must be non-negative for all values of x within its support, meaning that f(x) ≥ 0 for all x.
2. The integral of f(x) dx over the support of x must equal 1. This condition ensures that the total probability of all possible outcomes is equal to 1, which is a fundamental property of probability.
In mathematical terms, if f(x) is a PDF with support A, then the following conditions must be satisfied:

The solution to the differential equation [tex]\(\frac{du}{dt} = e^{3.4t} - 3.2u\)[/tex] with the given initial condition is [tex]\(u = \frac{1}{3.2} (e^{3.4t} - 10.52e^t)\)[/tex].

To find the solution u(t) from the given differential equation and initial condition, we can use the method of separation of variables.

The given differential equation is:

[tex]\(\frac{du}{dt} = e^{3.4t} - 3.2u\)[/tex]

To solve this, we'll separate the variables by moving all terms involving u to one side and all terms involving t to the other side:

[tex]\(\frac{du}{e^{3.4t} - 3.2u} = dt\)[/tex]

Next, we integrate both sides with respect to their respective variables:

[tex]\(\int \frac{1}{e^{3.4t} - 3.2u} du = \int dt\)[/tex]

The integral on the left side is a bit more involved. We can use substitution to simplify it.

Let [tex]\(v = e^{3.4t} - 3.2u\)[/tex], then [tex]\(dv = (3.4e^{3.4t} - 3.2du)\)[/tex].

Rearranging, we have [tex]\(du = \frac{3.4e^{3.4t} - dv}{3.2}\)[/tex].

Substituting these values in, the integral becomes:

[tex]\(\int \frac{1}{v} \cdot \frac{3.2}{3.4e^{3.4t} - dv} = \int dt\)[/tex]

Simplifying, we get:

[tex]\(\ln|v| = t + C_1\)[/tex]

where C₁ is the constant of integration.

Substituting back [tex]\(v = e^{3.4t} - 3.2u\)[/tex], we have:

[tex]\(\ln|e^{3.4t} - 3.2u| = t + C_1\)[/tex]

To find the particular solution that satisfies the initial condition u(0) = 3.6, we substitute t = 0 and u = 3.6 into the equation:

[tex]\(\ln|e^{0} - 3.2(3.6)| = 0 + C_1\)\\\(\ln|1 - 11.52| = C_1\)\\\(\ln|-10.52| = C_1\)\\\(C_1 = \ln(10.52)\)[/tex]

Thus, the solution to the differential equation with the given initial condition is:

[tex]\(\ln|e^{3.4t} - 3.2u| = t + \ln(10.52)\)[/tex]

Simplifying further:

[tex]\(e^{3.4t} - 3.2u = e^{t + \ln(10.52)}\)\\\(e^{3.4t} - 3.2u = e^t \cdot 10.52\)\\\(e^{3.4t} - 3.2u = 10.52e^t\)[/tex]

Finally, solving for u, we have:

To determine the radius of convergence, we can use the ratio test. In this case, we have a power series with coefficients determined by the expression[tex]|3x - 3|^5[/tex]. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. Taking the limit of [tex]|(3x - 3)^5 / (3x - 3)^5+3x - 3)||[/tex]as x approaches a fixed value will help us find the radius of convergence. Since the series converges when |3x - 3|^5 < 1 and diverges when |3x - [tex]3|^5 > 1,[/tex]we can solve for the critical point at which the inequality switches. Solving[tex]|3x - 3|^5 = 1[/tex] gives us x = 2/3 and x = 4/3. The distance between these two points is 2/3 - 4/3 = 2/3. Therefore, the radius of convergence is 1/3.
